BACKGROUND

Bone grafting is typically performed for spinal fusions, after cancerous bone removal, and in certain operations, e.g., plastic surgery. The iliac crest is often used as a donor site for autologous grafts. Complications collecting bone from the iliac crest include pain, nerve damage, hematoma and wound complications, avulsion of the anterior superior iliac spine (ASIS), hematoma, herniation of the abdominal cavity contents, and cosmetic deformity. Thus, it is desirable to develop materials and methods of forming bone that do not require harvesting bone from remote sites of the patient.

Synthetic bone grafts typically include a matrix that holds minerals and other salts. Natural bone has an intracellular matrix mainly composed of type I collagen, and some synthetic bone grafts include a collagen matrix. Synthetic bone grafts typically contain bone growth factors such as bone morphogenetic proteins (BMPs) because of their ability to induce ossification in the matrix material. Recombinant human BMP-2 has been approved by the FDA in synthetic bone grafts such as INFUSE™. INFUSE™ is approved for open tibial shaft fractures, lumbar interbody fusion, and sinus and alveolar ridge augmentations. However, the high cost and need for high concentrations of BMP-2 for treatment creates a barrier for routine clinical use. Thus, there is a need to identify additional compositions that can substitute or complement the use of BMPs in treating bone-related conditions.

References cited herein are not an admission of prior art.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 illustrates the BMP signaling pathway. Although it is not intended that embodiments of the disclosure be limited by any particular mechanism, it is believed that the embodiments may act through the BMP pathway. In the BMP pathway, BMP binds to the BMP receptor type II that in turn activates BMPR-1. Activated BMPR-1 phosphorylates receptor regulated Smads (Smad1/5/8) which form complexes with Smad4. Activated Smad complexes regulate gene expression of BMP-responsive genes. Noggin antagonizes signaling by binding to BMP.

DETAILED DISCUSSION Terms

“Ossification” refers to the process of laying down new bone by cells called osteoblasts. The term includes the growth in healing bone fractures treated by cast or by open reduction and stabilization by metal plate and screws. Ossification can also result in the formation of bone tissue in an extraskeletal location.

The term “bone morphogenetic protein” or “BMP” refers to any one of the family of growth factors or fragments thereof with the ability to induce the formation of bone and/or cartilage. The BMP receptors are typically serine-threonine kinases. It is not intended that BMP refer to any particular protein sequence and may or may not have certain glycosylation patterns attached thereto provided that the molecule has sufficient structural homology to any one of the known BMPs described below and retains some functional ability to promote bone growth, cartilage growth, or osteoblast differentiation. BMPs may be isolated from natural or non-natural sources, such as, but not limited to, recombinant or synthetic methods. References to BMPs generally or a specific BMP, e.g, BMP-2, includes recombinant or synthetically isolated versions unless otherwise provide for herein. Combinations of BMPs are contemplated. BMP-2 is known to induce bone and cartilage formation and play a role in osteoblast differentiation. BMP-3 is known to induce bone formation. BMP-4 is known to regulate the formation of teeth, limbs and bone from mesoderm and play a role in fracture repair. BMP-5 is known to function in cartilage development. BMP-6 is known to play a role in joint integrity and bone formation/repair. BMP-7 and BMP-9 are known to play a role in osteoblast differentiation. BMP-1 is a known metalloprotease that acts on procollagen I, II, and III and is involved in cartilage development.

As used herein, the term “derivative” refers to a structurally similar compound that retains sufficient functional attributes of the identified analogue. The derivative may be structurally similar because it is lacking one or more atoms, substituted, a salt, in different hydration/oxidation states, or because one or more atoms within the molecule are switched, such as, but not limited to, replacing an oxygen atom with a sulfur atom or replacing an amino group with a hydroxy group. The derivative may be a prodrug. Derivatives can be prepare by any variety of synthetic methods or appropriate adaptations presented in synthetic or organic chemistry text books, such as those provide in March's Advanced Organic Chemistry: Reactions, Mechanisms, and Structure, Wiley, 6th Edition (2007) Michael B. Smith or Domino Reactions in Organic Synthesis, Wiley (2006) Lutz F. Tietze.

The term “substituted” refers to a molecule wherein at least one hydrogen atom is replaced with a substituent. When substituted, one or more of the groups are “substituents.” The molecule may be multiply substituted. In the case of an oxo substituent (“═O”), two hydrogen atoms are replaced. Example substituents within this context may include halogen, hydroxy, alkyl, alkoxy, nitro, cyano, oxo, carbocyclyl, carbocycloalkyl, heterocarbocyclyl, heterocarbocycloalkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl, —NRaRb, —NRaC(═O)Rb, —NRaC(═O)NRaNRb , —NRaC(═O)ORb, —NRaSO2Rb, —C(═O)Ra, —C(═O)ORa, —C(═O)NRaRb, —OC(═O)NRaRb, —ORa, —SRa, —SORa, —S(═O)2Ra, —OS(═O)2Ra and —S(═O)2ORa. Ra and Rb in this context may be the same or different and independently hydrogen, halogen hydroxy, alkyl, alkoxy, alkyl, amino, alkylamino, dialkylamino, carbocyclyl, carbocycloalkyl, heterocarbocyclyl, heterocarbocycloalkyl, aryl, arylalkyl, heteroaryl, heteroarylalkyl.

The term “optionally substituted,” as used herein, means that substitution is optional and therefore it is possible for the designated atom to be unsubstituted.

As used herein, “subject” refers to any animal, preferably a human patient, livestock, or domestic pet.

As used herein, the terms “prevent” and “preventing” include the prevention of the recurrence, spread or onset. It is not intended that the present disclosure be limited to complete prevention. In some embodiments, the onset is delayed, or the severity is reduced.

As used herein, the terms “treat” and “treating” are not limited to the case where the subject (e.g. patient) is cured and the disease is eradicated. Rather, embodiments of the present disclosure also contemplate treatment that merely reduces symptoms, and/or delays disease progression.

As used herein, the term “calcium phosphate(s)” refers to minerals containing calcium ions together with orthophosphates, metaphosphates or pyrophosphates and optionally hydroxide ions. Tricalcium phosphate is a calcium phosphate with formula Ca₃(PO₄)₂. The common mineral apatite has the basic formula Ca₅(PO₄)₃X, where X is a ion, typically a halogen or hydroxide ion, or a mixture.

Evaluations of Compound Activity

BMP-2 and BMP-4 have been established to be important factors in embryonic skeletal development. BMP receptors are transmembrane receptors classified as type I or type II based on sequence homology and contain a Ser/Thr protein kinase domain. BMP ligand binding to type I receptor (BMPR-I) induces the association of BMPR-I and BMPR-II receptors, allowing the constitutively phosphorylated BMPR-II to phosphorylate and activate the latent BMPR-I. After activation of BMPR-I, the receptor regulated (R)-Smad1/5/8 is phosphorylated. Phosphorylation of R-Smad releases it from the receptor complex and forms hetero-complex associating with common Smad (Co-Smad, Smad4). Subsequently, R-Smad/Co-Smad complex translocates into the nucleus and regulates the transcription of target genes by functioning in concert with other proteins as transcription factors. See FIG. 1. BMP activity is regulated prior to receptor recognition by the presence of several structurally distinct extracellular BMP antagonists such as Noggin, follistatin, sclerostatin, chordin, DCR, BMPMER, cerberus, gremlin, DAN, and others.

Activity was evaluated by determining the potentiation of alkaline phosphatase activity in sub-optimal doses of BMP in the presence or absence of exogenously added noggin.

In some embodiments, these compositions can be created from polymers, bone granules, and ceramics such as calcium phosphates (e.g. hydroxyapatite and tricalcium phosphate), bioglass, and calcium sulphate.

Bioglass refers to materials of SiO₂, Na₂O, CaO, and P₂O₅ in specific proportions. The proportions differ from the traditional soda-lime glasses in lower amounts of silica (typically less than 60 mol %), higher amounts of sodium and calcium, and higher calcium/phosphorus ratio. A high ratio of calcium to phosphorus promotes formation of apatite crystals; calcium and silica ions can act as crystallization nuclei. Some formulations bind to soft tissues and bone, some only to bone, some do not form a bond at all and after implantation get encapsulated with non-adhering fibrous tissue, and others are completely absorbed overtime. Mixtures of 35-60 mol % SiO₂, 10-50 mol % CaO, and 5-40 mol % Na₂O bond to bone and some formulations bond to soft tissues. Mixtures of >50 mol % SiO₂, <10 mol % CaO, <35 mol % Na₂O typically intigrate within a month. Some CaO may be replaced with MgO and some Na₂O may be replaced with K₂O. Some CaO can be replaced with CaF₂.

Methods

Bone grafting is possible because bone tissue, unlike most other tissues, has the ability to regenerate if provided the space into which to grow with appropriate chemical signals. With regard to synthetic grafts, as native bone grows, it typically replaces most or all of the artificial graft material, resulting in an integrated region of new bone. However, with regard to certain embodiments of the disclosure, it is not intended that new bone must remove all artificial material.

The graft may be the result of a void created by surgical removal or created as a result of an attempt to correct a physical abnormality of a bone, such as but not limited to, cranial bones; frontal, parietal, temporal, occipital, sphenoid, ethmoid; facial bones; mandible, maxilla, palatine, zygomatic, nasal, lacrimal, vomer, inferior nasal conchae; shoulder girdle; scapula or shoulder blade, clavicle or collarbone; in the thorax; sternum, manubrium, gladiolus, and xiphoid process, ribs; in the vertebral column; cervical vertebrae, thoracic vertebrae; lumbar vertebrae; in the arms, humerus, radius, ulna; in the pelvis; coccyx; sacrum, hip bone (innominate bone or coxal bone); in the legs; femur, patella, tibia, and fibula. It is contemplated that the graft may be added for cosmetic purposes, e.g., cheek augmentation. In the case of a broken bone or removal of a bone during surgery, it may be desirable to secure movement of bone structure with a fixation system and remove the system after bone forms in the implanted graft.

With regard to prostheses, it may be desirable to grow bone between existing bone and an implanted device, or in preparation of an implanted device, such as in the case of a hip replacement, knee replacement, and dental implant, i.e., artificial tooth root used to support restorations that resemble a tooth or group of teeth.

In some embodiments, the disclosure relates to three-dimensional structures made of biocompatible and biodegradable bone graft materials in the shape of the bone infused with compositions disclosed herein to promote bone growth. Implants can be used to support a number of prostheses. A typical implant consists of a titanium device. In certain embodiments, the graft compositions disclosed herein contain implants.

With regard to a sinus augmentation or alveolar ridge augmentation, surgery may be performed as an outpatient under general anesthesia, oral conscious sedation, nitrous oxide sedation, intravenous sedation or under local anesthesia. Bone grafting is used in cases where there is a lack of adequate maxillary or mandibular bone in terms of depth or thickness. Sufficient bone is needed in three dimensions to securely integrate with the root-like implant. Improved bone height is important to assure ample anchorage of the root-like shape of the implant.

In a typical procedure, the clinician creates a large flap of the gingiva or gum to fully expose the bone at the graft site, performs one or several types of block and onlay grafts in and on existing bone, then installs a membrane designed to repel unwanted infection-causing bacteria. Then the mucosa is carefully sutured over the site. Together with a course of systemic antibiotics and topical antibacterial mouth rinses, the graft site is allowed to heal. The bone graft produces live vascular bone and is therefore suitable as a foundation for the dental implants.

In certain embodiments, the disclosure relates to methods of performing spinal fusion using compositions disclosed herein. Typically this procedure is used to eliminate the pain caused by abnormal motion of the vertebrae by immobilizing the vertebrae themselves. Spinal fusion is often done in the lumbar region of the spine, but the term is not intended to be limited to method of fusing lumbar vertebrae. Patients desiring spinal fusion may have neurological deficits or severe pain which has not responded to conservative treatment. Conditions where spinal fusion may be considered include, but are not limited to, degenerative disc disease, spinal disc herniation, discogenic pain, spinal tumor, vertebral fracture, scoliosis, kyphosis (i.e, Scheuermann's disease), spondylolisthesis, or spondylosis.

In certain embodiments, different methods of lumbar spinal fusion may be used in conjunction with each other. In one method, one places the bone graft between the transverse processes in the back of the spine. These vertebrae are fixed in place with screws and/or wire through the pedicles of each vertebra attaching to a metal rod on each side of the vertebrae. In another method, one places the bone graft between the vertebra in the area usually occupied by the intervertebral disc. In preparation for the spinal fusion, the disc is removed entirely. A device may be placed between the vertebrae to maintain spine alignment and disc height. The intervertebral device may be made from either plastic or titanium or other suitable material. The fusion then occurs between the endplates of the vertebrae. Using both types of fusion are contemplated.

In certain embodiments, the disclosure relates to methods of growing bone at a desired area by locally administering a pharmaceutical formulation containing a compound disclosed herein such as 2-(2-Methoxybenzylidene)-1-indanone; N-(4-arsonophenyl)glycine; 1,2-Benzenedicarboxylic acid, 1-(1-methylheptyl) ester; (4′-hydroxybiphenyl-4-yl)(phenyl)methanone; 2,2-dimethylchroman-6-carboxylic acid, (4,7-dihydroxy-8-methyl-2-oxo-2H-chromen-3-yl)amide; Ethyl 2-((4-chlorophenyl)thio)-1,3-benzothiazol-6-yl carbamate; Ethyl (2-(azepan-1-yl)benzo[d]thiazol-6-yl) carbamate; Porfiromycin; 1,3-benzodioxol-5-yl-[4-(3,4,5-trimethoxybenzoyl)-3-furyl]methanone; Tricinolone acetophenonide; 2,4-bis(3,4-dimethoxyphenyl)-4H-pyrano[3,2-c]chromen-5-one; Methyl 5-fluoro-4-methoxy-2,6-dioxohexahydro-5-pyrimidine carboxylate; 5-(naphthalen-1-yl)-1-phenyl-1h-tetrazole; 5-(2-phenylquinolin-4-yl)-1,3,4-oxadiazol-2-ol; N-[2,4,5-trimethyl-4-(trichloromethyl)cyclohexa-2,5-dien-1-ylidene]hydroxylamine; 4-benzoyl-3,4-dihydro-Benzo[f]quinoline-3-carbonitrile; 2-nitro-3-phenylspiro[cyclopropane-1,9′-fluorene]; 3-[4-(furan-2-ylmethyl)-5-sulfanylidene-1,2,4-dithiazolidin-3-ylidene]-1,1-dimethylthiourea; (6-acetamido-7-methyl-5,8-dioxo-2,3-dihydro-1H-pyrrolo[1,2-a]benzimidazol-3-yl) 2-methoxyacetate; 5-Iodo-1H-indole-2,3-dione; 4,5-dihydro-1,2,9,10-tetramethoxy dibenzo[de,g]quinoline-6-carboxylic acid, ethyl ester; [2,6-bis(2,4-dimethylphenyl)-4-(2-methoxyacetyl)oxy-phenyl] 2-methoxyacetate; 5,11-dimethyl-2-(2-piperidin-1-ylethyl)-6H-pyrido[4,3-b]carbazol-2-ium-9-ol; 2-[3-[[4-[(3-nitroacridin-9-yl)amino]phenyl]sulfamoyl] propyl]guanidine; 1-[[2-(dimethylamino)ethyl]amino]-7-hydroxy-4-methyl-9H-thioxanthen-9-one; 5-amino-1H-1,2,4-triazole-3-carboxylic acid, methyl ester; methyl N-cyano-N′-prop-2-en-1-ylcarbamimidothioate; 5,7-dinitro-8-quinolinol; 5-nitrosoquinolin-8-ol; Cantharidin; 1,7-Diaminoacridine; 3-Methyl-3-(1-naphthyl)-2-benzofuran-1(3H)-one; Dichlorolapachol; Lycobetaine; 6-(1-aziridinyl)-2,3-dihydro-3-(propionyl)-7-methyl-1H-Pyrrolo[1,8]-dione; 4-Nitroestrone 3-methyl ether; 5,11-dimethyl-6H-pyrido[4,3-b]carbazole-1-carboxamide hydrochloride; 5-Methoxysterigmatocysin; (6-acetamido-7-methyl-5,8-dioxo-2,3-dihydro-1H-pyrrolo[1,2-a]benzimidazol-3-yl) 2-methoxyacetate; Horminon; 7′,8′-dimethyl-2′-oxo-4′,4a′,6a′,7′-tetrahydro-2′H-spiro[oxirane-2,1′-pentaleno[1,6a-c]pyran]-5′-carboxylate; Nybomycin acetate; 5H-[1,6]indeno[1,2-c]isoquinoline-5,12-dione; 2,3-dimethoxy-6-methyl-Nitidine; Iproplatin; 3-[(deoxyhexosyl)oxy]-2-(3,4-dihydroxyphenyl)-6,8-dihdroxy-4H-1-Benzopyran-4-one; 2-O-benzyl 8-O-methyl 3-(4-methylphenyl)sulfonyl-4,5-dioxo-6H-pyrrolo[3,2-e]indole-2,8-dicarboxylate; 6-bromo-5,8-dihydroxy-7-[4-[2-(2-hydroxyethoxy)ethyl] piperazin-1-yl]naphthalene-1,4-dione; 5-methylbenzo[c]phenanthridin-5-ium-2,3,8,9-tetrol; (6-acetyl-4-oxo-1,3-diphenyl-2-sulfanylidenethieno[2,3-d]pyrimidin-5-yl)-2,4-dichlorobenzoate; N—[C-[4-[bis(2-cyanoethyl)amino]-2-methylphenyl]-N-(4-methylanilino)carbonimidoyl]imino-4-methylbenzamide; Gelcohol; Curcumin; Tirandamycin; Noscapine; Aristolochic acid; Himbacine; Fumagillin; Fumitremorgin C; Physalin B; derivatives, or salts thereof, to the area of desired bone growth with or without the presence of a graft composition or bone growth matrix optionally in combination with a growth factor such as a bone morphogenetic protein.

Therapeutic Applications

In some embodiments, the disclosure relates to pharmaceutical compositions comprising compounds disclosed herein for therapeutic applications. In some embodiments, the disclosure relates to methods of treating bone degenerative disorders, such as osteoporosis, osteitis deformans (“Paget's disease of bone”), bone metastasis (with or without hypercalcaemia), multiple myeloma, primary hyperparathyroidism, or osteogenesis imperfecta. Osteoporosis is a disease of bones that leads to an increased risk of fracture. In osteoporosis, the bone mineral density (BMD) is reduced, bone microarchitecture is disrupted, and the amount and variety of proteins in bone is altered. Osteoporosis is most common in women after menopause, when it is called postmenopausal osteoporosis, but may also develop in men, and may occur in anyone in the presence of particular hormonal disorders and other chronic diseases or as a result of medications, specifically glucocorticoids, when the disease is called steroid- or glucocorticoid-induced osteoporosis (SIOP or GIOP).

Osteoporotic fractures are those that occur in situations where healthy people would not normally break a bone; they are therefore regarded as fragility fractures. Typical fragility fractures occur in the vertebral column, rib, hip and wrist. The diagnosis of osteoporosis can be made using conventional radiography by measuring the bone mineral density (BMD).

Diabetes mellitus type II (Diabetes type II or noninsulin-dependent diabetes mellitus (NIDDM) or adult-onset diabetes) is a metabolic disorder that is characterized by high blood glucose in the context of insulin resistance and/or insulin deficiency. This is in contrast to diabetes mellitus type 1, in which there is an absolute insulin deficiency typically due to destruction of islet cells in the pancreas.

Bottcher et al. report that adipose tissue expression and genetic variants of the bone morphogenetic protein receptor 1A gene (BMPR1A) are associated with human obesity. See Diabetes, 2009, 58:2119-2128. Although it is not intended that ceratin embodiments of the disclosure be limited by any particular mechanism, it is believed that inducing BMP signaling improves the production of brown fat or brown-like fat causing increase metabolic rates to reduce white fat content. It has been reported that there is cross talk between insulin and bone morphogenetic protein signaling systems in brown adipogenesis. See Wee Zhang et al, MOLE CELL BIO, 2010, 30(17): 4224-4233. BMP4-mediated brown fat-like changes are reported in white adipose tissue alter glucose and energy homeostasis. See Qian et al., PNAS, 2013, 110(9) E798-E807. Brown-fat paucity due to impaired BMP signaling is reported to induce compensatory browning of white fat. See Schulz et al., Nature, 2013, 49:379-383.

Formulations

Pharmaceutical compositions disclosed herein may be in the form of pharmaceutically acceptable salts, as generally described below. Some preferred, but non-limiting examples of suitable pharmaceutically acceptable organic and/or inorganic acids are hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, acetic acid and citric acid, as well as other pharmaceutically acceptable acids known per se (for which reference is made to the references referred to below).

When the compounds of the disclosure contain an acidic group as well as a basic group, the compounds of the disclosure may also form internal salts, and such compounds are within the scope of the disclosure. When the compounds of the disclosure contain a hydrogen-donating heteroatom (e.g. NH), the disclosure also covers salts and/or isomers formed by transfer of said hydrogen atom to a basic group or atom within the molecule.

Pharmaceutically acceptable salts of the compounds include the acid addition and base salts thereof. Suitable acid addition salts are formed from acids which form non-toxic salts. Examples include the acetate, adipate, aspartate, benzoate, besylate, bicarbonate/carbonate, bisulphate/sulphate, borate, camsylate, citrate, cyclamate, edisylate, esylate, formate, fumarate, gluceptate, gluconate, glucuronate, hexafluorophosphate, hibenzate, hydrochloride/chloride, hydrobromide/bromide, hydroiodide/iodide, isethionate, lactate, malate, maleate, malonate, mesylate, methylsulphate, naphthylate, 2-napsylate, nicotinate, nitrate, orotate, oxalate, palmitate, pamoate, phosphate/hydrogen phosphate/dihydrogen phosphate, pyroglutamate, saccharate, stearate, succinate, tannate, tartrate, tosylate, trifluoroacetate and xinofoate salts. Suitable base salts are formed from bases which form non-toxic salts. Examples include the aluminium, arginine, benzathine, calcium, choline, diethylamine, diolamine, glycine, lysine, magnesium, meglumine, olamine, potassium, sodium, tromethamine and zinc salts. Hemisalts of acids and bases may also be formed, for example, hemisulphate and hemicalcium salts. For a review on suitable salts, see Handbook of Pharmaceutical Salts: Properties, Selection, and Use by Stahl and Wermuth (Wiley-VCH, 2002), incorporated herein by reference.

The compounds described herein may be administered in the form of prodrugs. A prodrug can include a covalently bonded carrier which releases the active parent drug when administered to a mammalian subject. Prodrugs can be prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds. Prodrugs include, for example, compounds wherein a hydroxy group is bonded to any group that, when administered to a mammalian subject, cleaves to form a free hydroxy group. Examples of prodrugs include, but are not limited to, acetate, formate, and benzoate derivatives of alcohol functional groups in the compounds. Methods of structuring a compound as prodrugs can be found in the book of Testa and Mayer, Hydrolysis in Drug and Prodrug Metabolism, Wiley (2006). Typical prodrugs form the active metabolite by transformation of the prodrug by hydrolytic enzymes, the hydrolysis of amide, lactams, peptides, carboxylic acid esters, epoxides or the cleavage of esters of inorganic acids.

Pharmaceutical compositions for use in the present disclosure typically comprise an effective amount of a compound and a suitable pharmaceutical acceptable carrier. The preparations may be prepared in a manner known per se, which usually involves mixing the at least one compound according to the disclosure with the one or more pharmaceutically acceptable carriers, and, if desired, in combination with other pharmaceutical active compounds, when necessary under aseptic conditions. Reference is made to U.S. Pat. Nos. 6,372,778, 6,369,086, 6,369,087 and 6,372,733 and the further references mentioned above, as well as to the standard handbooks, such as the latest edition of Remington's Pharmaceutical Sciences.

Generally, for pharmaceutical use, the compounds may be formulated as a pharmaceutical preparation comprising at least one compound and at least one pharmaceutically acceptable carrier, diluent or excipient and/or adjuvant, and optionally one or more further pharmaceutically active compounds.

The pharmaceutical preparations of the disclosure are preferably in a unit dosage form, and may be suitably packaged, for example in a box, blister, vial, bottle, sachet, ampoule or in any other suitable single-dose or multi-dose holder or container (which may be properly labeled); optionally with one or more leaflets containing product information and/or instructions for use. Generally, such unit dosages will contain between 1 and 1000 mg, and usually between 5 and 500 mg, of the at least one compound of the disclosure, e.g. about 10, 25, 50, 100, 200, 300 or 400 mg per unit dosage.

The compounds can be administered by a variety of routes including the oral, ocular, rectal, transdermal, subcutaneous, intravenous, intramuscular or intranasal routes, depending mainly on the specific preparation used. The compound will generally be administered in an “effective amount”, by which is meant any amount of a compound that, upon suitable administration, is sufficient to achieve the desired therapeutic or prophylactic effect in the subject to which it is administered. Usually, depending on the condition to be prevented or treated and the route of administration, such an effective amount will usually be between 0.01 to 1000 mg per kilogram body weight of the patient per day, more often between 0.1 and 500 mg, such as between 1 and 250 mg, for example about 5, 10, 20, 50, 100, 150, 200 or 250 mg, per kilogram body weight of the patient per day, which may be administered as a single daily dose, divided over one or more daily doses. The amount(s) to be administered, the route of administration and the further treatment regimen may be determined by the treating clinician, depending on factors such as the age, gender and general condition of the patient and the nature and severity of the disease/symptoms to be treated. Reference is again made to U.S. Pat. Nos. 6,372,778, 6,369,086, 6,369,087, and 6,372,733 and the further references mentioned above, as well as to the standard handbooks, such as the latest edition of Remington's Pharmaceutical Sciences.

For an oral administration form, the compound can be mixed with suitable additives, such as excipients, stabilizers or inert diluents, and brought by means of the customary methods into the suitable administration forms, such as tablets, coated tablets, hard capsules, aqueous, alcoholic, or oily solutions. Examples of suitable inert carriers are gum arabic, magnesia, magnesium carbonate, potassium phosphate, lactose, glucose, or starch, in particular, corn starch. In this case, the preparation can be carried out both as dry and as moist granules. Suitable oily excipients or solvents are vegetable or animal oils, such as sunflower oil or cod liver oil. Suitable solvents for aqueous or alcoholic solutions are water, ethanol, sugar solutions, or mixtures thereof. Polyethylene glycols and polypropylene glycols are also useful as further auxiliaries for other administration forms. As immediate release tablets, these compositions may contain microcrystalline cellulose, dicalcium phosphate, starch, magnesium stearate and lactose and/or other excipients, binders, extenders, disintegrants, diluents and lubricants known in the art.

When administered by nasal aerosol or inhalation, the compositions may be prepared according to techniques well-known in the art of pharmaceutical formulation and may be prepared as solutions in saline, employing benzyl alcohol or other suitable preservatives, absorption promoters to enhance bioavailability, fluorocarbons, and/or other solubilizing or dispersing agents known in the art. Suitable pharmaceutical formulations for administration in the form of aerosols or sprays are, for example, solutions, suspensions or emulsions of the compounds of the disclosure or their physiologically tolerable salts in a pharmaceutically acceptable solvent, such as ethanol or water, or a mixture of such solvents. If required, the formulation can also additionally contain other pharmaceutical auxiliaries such as surfactants, emulsifiers and stabilizers as well as a propellant.

For subcutaneous or intravenous administration, the compounds, if desired with the substances customary therefore such as solubilizers, emulsifiers or further auxiliaries are brought into solution, suspension, or emulsion. The compounds of formula I can also be lyophilized and the lyophilizates obtained used, for example, for the production of injection or infusion preparations. Suitable solvents are, for example, water, physiological saline solution or alcohols, e.g. ethanol, propanol, glycerol, sugar solutions such as glucose or mannitol solutions, or mixtures of the various solvents mentioned. The injectable solutions or suspensions may be formulated according to known art, using suitable non-toxic, parenterally-acceptable diluents or solvents, such as mannitol, 1,3-butanediol, water, Ringer's solution or isotonic sodium chloride solution, or suitable dispersing or wetting and suspending agents, such as sterile, bland, fixed oils, including synthetic mono- or diglycerides, and fatty acids, including oleic acid.

When rectally administered in the form of suppositories, the formulations may be prepared by mixing the compounds of formula I with a suitable non-irritating excipient, such as cocoa butter, synthetic glyceride esters or polyethylene glycols, which are solid at ordinary temperatures, but liquefy and/or dissolve in the rectal cavity to release the drug.

In certain embodiments, it is contemplated that these compositions can be extended release formulations. Typical extended release formations utilize an enteric coating. Typically, a barrier is applied to oral medication that controls the location in the digestive system where it is absorbed. Enteric coatings prevent release of medication before it reaches the small intestine. Enteric coatings may contain polymers of polysaccharides, such as maltodextrin, xanthan, scleroglucan dextran, starch, alginates, pullulan, hyaloronic acid, chitin, chitosan and the like; other natural polymers, such as proteins (albumin, gelatin etc.), poly-L-lysine; sodium poly(acrylic acid); poly(hydroxyalkylmethacrylates) (for example poly(hydroxyethyl methacrylate)); carboxypolymethylene (for example Carbopol™); carbomer; polyvinyl pyrrolidone; gums, such as guar gum, gum arabic, gum karaya, gum ghatti, locust bean gum, tamarind gum, gellan gum, gum tragacanth, agar, pectin, gluten and the like; poly(vinyl alcohol); ethylene vinyl alcohol; polyethylene glycol (PEG); and cellulose ethers, such as hydroxymethylcellulose (HMC), hydroxyethylcellulose (HEC), hydroxypropylcellulose (HPC), methylcellulose (MC), ethylcellulose (EC), carboxyethylcellulose (CEC), ethylhydroxyethyl cellulose (EHEC), carboxymethylhydroxyethylcellulose (CMHEC), hydroxypropylmethyl-cellulose (HPMC), hydroxypropylethylcellulose (HPEC) and sodium carboxymethylcellulose (Na CMC); as well as copolymers and/or (simple) mixtures of any of the above polymers. Certain of the above-mentioned polymers may further be crosslinked by way of standard techniques.

The choice of polymer will be determined by the nature of the active ingredient/drug that is employed in the composition of the disclosure as well as the desired rate of release. In particular, it will be appreciated by the skilled person, for example in the case of HPMC, that a higher molecular weight will, in general, provide a slower rate of release of drug from the composition. Furthermore, in the case of HPMC, different degrees of substitution of methoxyl groups and hydroxypropoxyl groups will give rise to changes in the rate of release of drug from the composition. In this respect, and as stated above, it may be desirable to provide compositions of the disclosure in the form of coatings in which the polymer carrier is provided by way of a blend of two or more polymers of, for example, different molecular weights in order to produce a particular required or desired release profile.

Microspheres of polylactide, polyglycolide, and their copolymers poly(lactide-co-glycolide) may be used to form sustained-release protein or compound delivery systems. Proteins and/or compounds can be entrapped in the poly(lactide-co-glycolide) microsphere depot by a number of methods, including formation of a water-in-oilemulsion with water-borne protein and organic solvent-borne polymer (emulsion method), formation of a solid-in-oil suspension with solid protein dispersed in a solvent-based polymer solution (suspension method), or by dissolving the protein in a solvent-based polymer solution (dissolution method). One can attach poly(ethylene glycol) to proteins (PEGylation) to increase the in vivo half-life of circulating therapeutic proteins and decrease the chance of an immune response.

EXPERIMENTAL Compound Screenings

The BMP-potentiating activities of compounds are evaluated by monitoring several markers of the osteoblastic phenotype corresponding to various time points during phenotype differentiation of C2C12 cells towards terminally differentiated osteoblasts.

Cell Culture

Mouse C2C12 cells and Dulbecco's modified Eagle's medium (DMEM) were purchased from ATCC (Manassas, Va.). The non-heat inactivated fetal bovine serum (FBS) was purchased from HyClone Laboratories, Inc. (Logan, Utah). The C2C12 cells at passages 5 to 10 were subcultured in T-75 cm² flasks in DMEM supplemented with 10% FBS at 37° C. in 5% CO₂ with humidification. When the flasks reached 80% confluence, the cells were trypsinized and seeded in triplicate.

Alkaline Phosphatase (ALP) Assay

The C2C12 cells were plated at 200,000 cells/well in 6-well plates and grown overnight in DMEM containing 10% FBS. On day 2, the culture medium was replaced with DMEM containing 2% FBS and the cells were treated with various concentrations of compound for 24 hours. On day 3, the culture medium was replaced with DMEM containing 2% FBS and the cells were treated with 50 ng/ml of BMP-2 and various concentrations of compound for 72 hours. The cells were washed with phosphate-buffered saline (PBS) and lysed by addition of lysis buffer (10 mM Tris-HCl pH 8.0, 1 mM MgCl₂ and 1.0% Triton X-100). The cell lysates were centrifuged for 5 minutes at 13,000×g. The supernatant was removed and the aliquots were assayed for ALP activity and protein amount. The ALP activity was measured in triplicate using an ALP assay kit (Sigma-Aldrich, St. Louis, Mo.) in microtiter plates. The protein amount was determined with Bio-Rad protein assay reagent (Bio-Rad, Hercules, Calif.) using bovine serum albumin (BSA) as a standard. The ALP activity (nmoles of p-nitrophenol per ml) was normalized to the protein amount (nmoles of p-nitrophenol per μg).

BMP-Noggin Competitive Alkaline Phosphatase (ALP) Assay

The C2C12 cells were plated at 200,000 cells/well in 6-well plates and grown overnight in DMEM containing 10% FBS. On day 2, the culture medium was replaced with DMEM containing 2% FBS and the cells were treated with 90-100 ng/ml of BMP-2 (as noted in each experiment), various concentrations of compound, and 100-120 ng/ml of noggin (as noted in each experiment) for 72 hours. The cells were washed with phosphate-buffered saline (PBS) and lysed by addition of lysis buffer (10 mM Tris-HCl pH 8.0, 1 mM MgCl₂ and 1.0% Triton X-100). The cell lysates were centrifuged for 5 minutes at 13,000×g. The supernatant was removed and the aliquots were assayed for ALP activity and protein amount. The ALP activity was measured in triplicate using an ALP assay kit (Sigma-Aldrich, St. Louis, Mo.) in microtiter plates. The protein amount was determined with Bio-Rad protein assay reagent (Bio-Rad, Hercules, Calif.) using bovine serum albumin (BSA) as a standard. The ALP activity (nmoles of p-nitrophenol per ml) was normalized to the protein amount (nmoles of p-nitrophenol per μg).
